ABSTRACT:
A novel coating agent for solid medicaments containing a hydrogel-like substance of a water-insoluble hydroxypropyl cellulose having 5-16% by weight of a hydroxypropoxy group or the dry powder of a hydrogel-like substance. By coating solid medicaments with the coating agent, solid medicaments having high impact resistance and showing very less aging can be provided advantageously in industry.
